For anyone interested in radio history — specifically Grigsby-Grunow history — this is a very good article by Paul Turney at https://www.antiqueradio.com/SepOct10_Turney_Grigsby-Grunow_Part1.html.
It’s the first of a two part series and covers the company history from inception to impending bankruptcy.
Unfortunately, he does not cover the GG relationship with Rogers, nor does he mention GG’s purchase of the Columbia Phonograph and Record Co. (yes, THAT Columbia) during the firm’s almost manic expansion during the late 1920’s and early 1930’s. It was this spending binge which most likely killed GG.
